Nuclear power’s new rule book: Managing uncertainty in efficiency, safety, and independence
The U.S. nuclear industry is standing at its most volatile regulatory moment yet—one that will shape the trajectory and the safety of the industry for decades to come. Recent judicial, legislative, and executive actions are rewriting the rules governing the licensing and regulation of nuclear power reactors. Although these changes are intended to promote and accelerate the deployment of new nuclear energy technologies, the collision of multiple legal shifts—occurring simultaneously and intersecting with profound technological uncertainties—is overwhelming the Nuclear Regulatory Commission and threatening to destabilize investor and industry expectations.

Potential safety advantages are achievable through the use of advanced fuel cycles, which eliminate the need to breed and fuel tritium, and produce fewer neutrons. In this work, the operational radiological hazards associated with the deuterium-tritium (DT), deuterium-deuterium (DD) and deuterium-helium-3 (DHe) fusion fuel cycles have been compared. The advanced fuels have a clear advantage over the DT fuel cycle in terms of tritium hazard. In terms of activation and waste disposal hazards, the operational safety advantages of the advanced fuels are less clear, and appear to be strongly material dependent.a On assignment from the Canadian Fusion Fuels Technology Project (CFFTP).
